How To Build A Harness With Jev | A LangChain x TypeSafe Conversation
TypeSafe's Jev is a new 'System 1' model class making fast type-safe decisions rather than generating text.
“Jev does not generate text. It is not a generative AI in that sense... Jev is about making fast decisions from specifically well-scoped questions with type safe schemas for each of them.”
TypeSafe and LangChain introduced Jev, a 'System 1' model that makes fast, well-scoped decisions with type-safe schemas instead of generating text, positioned as a code-first API for machine-to-machine decision points currently handled by heavy LLMs. It signals a trend toward lightweight, specialized decision models embedded in software, but this is a webinar/demo rather than a major industry announcement.
